Is their a way such as site:http;//www.yoursite.com or link: http;//wwwyoursite.com (semicolon on purpose) that will tell you what sites have backlinks from your site in Google's list of backlinks. Know what I mean? For example, I want to know who and how many people are benefitting from having a link on my site.
There's a new MSN operator called linkfromdomain: but obviously that will only tell you what MSN knows about. It will give you an idea though.
